Communication portable terminal device

Abstract

It is an object of the invention to emit a light in order to brighten a large area by a single light source. The invention provides a communication portable terminal device including a single LED (51) disposed in an upper housing (1) and a light emitting panel (4) disposed on the upper housing (1) for emitting a light like a plane by a light emitted from the LED (51), the light emitting panel (4) including a light transmitting member (40) having an incident plane (42) on which the light emitted from the LED (51) is incident and a light emitting plane (44) for emitting a light like a plane by the light emitted from the LED (51), and a reflecting film (41) and a print film (43) provided on a surface and a back face of the light transmitting member (40) for reflecting the light emitted from the LED (51) and incident on the incident plane (42) of the light transmitting member (40) many times between the surface and the back face, thereby guiding the light to the light emitting plane (44).

Description

TECHNICAL FIELD [0001] The present invention relates to a communication portable terminal device, and more particularly to a communication portable terminal device capable of giving a notice that there is a call from a calling destination or an incoming call of a mail through a light emission in a wide area. BACKGROUND ART [0002] In a cell phone, as is well known, it is possible to inform a user that there is a call from a calling destination or an incoming call of a mail through a ring or a ringer tone. However, it is not preferable to make a sound depending on a place of use. For this reason, a cell phone for giving a notice of a call and an incoming call through a vibration (a vibrator) in place of a sound has also spread widely. [0003] Moreover, there has also been known a cell phone including a light emitting unit having a light source in order to give a notice of a call and an incoming call through a light in place of the sound and the vibration. In particular, the notice of t...

Benefits of technology

[0010] Accordingly, the light emitted from the light source which is transmitted through the inner part of the light transmitting member is repetitively reflected continuously plural times between the reflecting units provided on both of the front face and the back face of the light transmitting member without causing a phenomenon such as a leakage to an outside, an attenuation or an absorption. Consequently, the light can be propagated to the light emitting unit so that the light emitting unit can be caused to carry out a surface emission.

[0012] Accordingly, it is possible to form the reflecting units by a simple method through printing. Consequently, a manufacturing cost can be reduced. In addition, if the reflecting unit has a high reflectance, various colors can be selected. By combining the print color and a color of the light emitted from the light source, therefore, it is also possible to form various mixed colors, thereby causing the light emitting unit to carry out the surface emission.

[0014] Accordingly, the light emitted from the light source can be fetched (incident) at an almost equal rate in various directions through the incident portion of the light transmitting member. Consequently, it is possible to implement a uniform surface emission in the light emitting unit without emitting a light partially to only a part of the light emitting unit.

Problems solved by technology

However, it is not preferable to make a sound depending on a place of use.

In some cases in which a small light emitting unit is provided to emit a light from a small area in the former method, for example, it is hard to visually recognize the emission of the light.

There is also a possibility that the light emitting operation might be known with a delay and a phone might be thus hung up before a response to a call from a partner or a calling state might be missed, resulting in a failure in calling.

On the other hand, in some cases in which the type for causing the display unit to emit a light in the latter method has such a structure as to cause a part of the display unit to locally emit a light, it is hard to visually know the call in the same manner as in the former case.

In the case in which the light emitting unit has a large area, however, it is hard to obtain a sufficient amount of a light emitted in a light emitting operation to be carried out by one light source (LED).

Corresponding to the use of the light sources, however, a built-in battery is consumed greatly with an increase in a consumed power.
